I'd like to vote for salamence-mega to be moved to S rank.

0- Atk Aerilate Mega Salamence Return vs. 0 HP / 0 Def Gengar: 127-151 (94 - 111.8%) -- guaranteed OHKO after Stealth Rock

STAB boosted aerialate return will put a huge dent in almost anything. Not to mention that salamence-mega has been banished to Ubers on smogon.

Another case is that of mawile-mega.

252+ Atk Huge Power Mega Mawile Sucker Punch vs. 252 HP / 0 Def Aegislash-Shield: 108-128 (64.6 - 76.6%) -- guaranteed 2HKO

252+ Atk Huge Power Mega Mawile Play Rough vs. 0 HP / 0- Def Shaymin: 186-219 (106.2 - 125.1%) -- guaranteed OHKO

Sableye-mega is another case, being able to stall most opponents into obvilion with will-o-wisp and recover.
